AROHIBALD PAUL, OF GOHOES, NEW YORK.

MACHINE FOR WINDINQ BOBBINS.

SPECIFICATION forming part of Letters Patent No. 233,112, dated October 12, 1880.

" Application filed April 29, 1880. (Model) To all whom it may concern Be it known that I, ARGHIBALD PAUL, of the city of Cohoes, in the county of Albany and State of New York, have invented a new .and useful Machine for Winding Bobbins, of

and-my invention consists in certain details of construction fully described hereinafter, and pointed out in the claims, forinsuring the proper disposition of the yarn, maintaining the requisite tension, preventing breakage,

andreadily adapting the machines to yarns of difl'erent characters.

In the drawings, Figure 1 is a front or longitudinal elevation, and Fig.2 is an ,end elevation, of my bobbin-winder. Fig. 3 is a sec- 'tion'al view taken on the line as, Fig. 1, ex-

. hibiting the yarn-tension device.

Fig.4isa rear view of a portion of the thread-distributing devices. Fig. 5 is a sectional view of the adjustable pulley, from which a round band runs to and rotates the pulley on the bobbinspindle. A sectional view of the latter pulley is shown in Fig. 6. Fig. 7 represents a view of a part of the screw and spiral gear which, in connection with the hinged weighted arm shown in Fig. 8, carries the bobbin back from the winding device as it is being filled. Fig. 9 1s a perspective View of the reciprocating comb which disengages the knots and ,protuberances on the yarn. Fig; 10 is a longitudinal View of the device which imparts the requisite motion to the comb shown in Fig. 9. Fig. 11 exhibits a detached portion of the end frame-work of the machine. Fig. 12 is a section on the line 3 y, Fig. 11, showing the stud in the slot of the frame. Fig. 13 is a perspective view of part of the frame and the bobbin. shaft, bobbin,and the appliances more immediately connected with the laying of the thread upon the bobbin and the movements of the bobbin-shaft. Fig. 14 is a detached perspective view, showing the rear of the bobbin and the devicefor connecting it to the spindle.

B, and the cross-ties B B constitute the prin- 6o cipal portion of the frame-work of the machine. The main driving-shaft 0 turns in. suitable hearings in the frame-work of the machine, and secured to said shaft is acircular orflangeshaped collar, d, which, with the adjustable portion d, that is fitted to slide on the shaft withoutturning thereon, constitutes the driving-pulley. The two portions of said pulley have their adjacent faces inclined toward each other, so as to form an annular V-shaped 7o groove when brought together to compress the band 6, which in turn imparts a rotary motion to the grooved pulley F, through which the bobbin spindle G is inserted, and which is made to revolve therewith by any of the wellknown means.

The loose portion d of the compound pulley is operated by means of the shipper-lex er h, as will be more fully understood by reference to the drawings. made to recede from the part d the round band is left free from contact with the pulley, as shown in the sectional view, Fig. 5.

Asmall pulley, i, is secured to the outerend of shaft 0. A much larger pulley, K, is fitted to turn on a suitable stud-pin, t affixed in the curved slot Z in the frame A by means of a nut, so as to be adjusted as shown in Figs. 11 and 12. A band, m, encompasses pulleys t and K, and communicates motion to pulleyK from pulley '5.

Gears N, of varying diameters, may be secured successively to pulley K.

The gear N meshes into gear N, as shown in Fig. 2, and is secured to the outer end of 5 the heart-cam shaft, for the purpose of imparting the requisite motion to the traverse-carriage 0 in the usual way by means of the heart-cams p p.

The curved slot l (shown in Fig. 11) is in- When the part d is So tended to preserve a uniform strain on the belt at whenever the stud-pin it is adjusted in the slot 2', to accommodate itself to the different diameters of gears N N. The object of changing gears is to increase or diminish the speed of the motion of the traverse-carriage, (which carries the yarn-distributing device and automatic bobbin-carrier,) which is rendered nec essary by the varying fineness of the yarn used, a coarse yarn requiring a more rapid traverse and bobbin-feed motion than a fine yarn, the bobbin, of course, revolving at a uniform speed.

On the traverse-frame (J is mounted the thread or yarn carrying apparatus, which also embraces the device which causes the bobbin to recede as the sameis being filled with yarn, all of which is constructed substantially as follows: A bent rod or arm, 1", is aflixed to the bracket Q, while a loosely-hinged lever, s, rises upward in an oblique direction, and is so formed as to quite touch the arm 1* when the yarn environs both, as will be seen in Figs. 1, 2, and 4, at t.

At the inner side of the bracket Q is pivoted a weighted pawl, 11, having a beveled side adapted to engage with a spiral gear, V, at the end of a screw-shaft, V, that turns freely without sliding in the frame of the machine parallel to the spindle G. When the yarn t breaks then the hinged lever 8 falls away from the arm 1' and raises the weighted pawl 11. to such an extent as not to touch or rotate the spiral gear V, afiixed to screw V, while the bracket carrying said pawl u is being moved forward and backward with it longitudinally with respect to the axis of the screw V.

The arm Y, Fig. 8, is hinged to the bobbinspindle G, between two collars, t t secured to the said spindle. Said arm has at its outer end a half-nut adapted to the screw-shaft V, the rotation of which carries the bobbin-spindle and its appendages longitudinally away from the yarn distributing or traversing apparatus, as will be readily understood, the screw V being intermittently rotated by the pawl u. The knob or ball-weight a,in conjunction with the spring a serves to keep the halfnut formed in the arm Y in proper contact with the thread of the screw V. When the bobbin is full of yarn (which has been wound thereon) it will have receded from the front of the machine, where it was placed when empty, to the rear, when the operator removes it from spindle G and lifts the ball end of the hinged arm Y from contact with the threads of the screw V and moves the bobbin-spindle longitudinally through its hearings to the front of the machine forthe reception of anotherempty bobbin.

In the frame of the machine turns a rockshaft, B having a spiral projection, 8 which enters between studs 8 s of a bar, 02. The rocking of the shaft will thereby cause said bar to reciprocate in a longitudinal direction,

carrying with it the comb Dfithatis designed for the purpose of disengaging knots or lumps from the yarn t, which passes and repasses in close proximity to a suitable pin or surface, f between which and the said comb D the yarn is drawn.

The comb has a slot, 19 Fig. 9, to receive the securing-bolt, and is thus transversely adjustable on the bar 0 to correspond with the fineness of yarn used. The principal object of imparting to the comb D a reciprocating motion is to prevent the deposit of the yarnlumps so much in one place as to clog the comb.

The shaft B is rocked from the traverse-carriage O by a lever, 1, slotted at the lower end to receive a pin on said carriage, and terminating in a toothed segment, a, gearing with a toothed segment on an arm, 2, of the rockshaft B, and from the latter a rocking motion is imparted to a shaft, E, through the medium of geared arms 3 and 4, as shown in Figs. 1 and 2.

I do not limit myself to this mode of communicatin g rocking motion to the shafts E B from the traverse-carriage. Adjustable projections g g are attached to the rock-shaft E and between the two extends the end of a stationary arm, h, secured to rail 1', (see Fig. 3,) and the movements of the rock-shaft are so timed that as the yarn t is being wound upon the smallest diameter of the bobbin the projectiou y will approach the end of the arm h and impart an increased tension to the yarn.

The yarn is carried from the cop Z upward around the projection g, under the arm h around the projection thence between the pin f and comb D, then around the hinged lever s and around the arm r to the bobbin W.

It will be seen that the yarn takes aless circuitous course around the projections g g and arm h when the shaft E is rocked forward, which occurs when the yarn is to be wound on the largest diameter of the bobbin.

I claim- 1. The frame having a curved slot, 1, stud t adjustable therein, pulley K, and gear N, turnin g on said stud, in combination with the shaft 0, provided with pulleys d, d, and i, the spindle G, pulley F, the belts e and m, the gear N, and appliances connected therewith fordistributing the yarn upon the bobbin K, substantially as set forth.
